riihe subject niatter et' this application is the construction and arrangement of a deviee tor opening and closing' the end ot a submarino vessel to provide .toroiiierating a torpedo tube. fin vessels; of thie type the torpedo tzuhe usually located at the forward end ot the vessel and has its mouth provided therefor. lt is necessary to provide a cover which will elette this' opening from the outside n'heu the torpedo tuhe is I not in use and it: important that this cover he so Constructed as: to

or elosed freni the interior ot the ves-sel.

'the novel featuresy ot eonstruetion ot th timer or eap and nieansv ,l'or operatingr the naine Vwill he more fully deserihed in eonneetiou with the deseriptiou ot' the ernhodinient ot the invention illustrated In the ae einnparrving dra wings in ivhieh similar parts y ,lt`ig11re l is' a. leertional side elevation o'lV a t ion ot the forward ein! ot' a suluuarine 1 por vessel. Figi; :l is a, plan vieiv ot the saine.

'the hull or hotly portion ot the vessel is shown mouth lilline; oi' the hull l..

fr rap 3E is hinged io the hull l in the. manner shown in the drawinge. lfheu the rap $5 is elosed the opening in the torward und of the hull l and the mouth o'tlthe torpedo tuhe is (closed therein' against. the entry of water.

Attaehed to the rap il is a segment. ot ay wernrgear /lmenhingg with a worin 5 whieh it; mounted upon and operated hy a shaft, (3. 'lfhe shaft (l extends from the exterior to the interior ot' the vessel, shown, and is provided at its inner end with a hand-ivlieel 7.

T his thickened portion is important when the torpedo tube is located at the forward g end of the vessel for the reason that, on aol count oi its force, the eap forming the Vnose ,l of the vee-sel would receive the full compact i and shock if the 'vessel were driven against any obstruction.

i between the ea p and hull of the vessel.

i It; will thus he seen that a simple and i substantial means tor closing the mouth of the torpedo tube when not in use is provided and that the device, whieh is necessarily 1oi rated on the outside of the vessel, is readily f operated "rom the interior thereof. i' What we elaim is: i .in combination with a submarine vessel l having,1 an openingl at one end thereof, of a torpedo tnhe having its mouth filling said y opening, a hinged eap having a thickened s0 l eentral portion and provided with a gear atl tuehed thereto outside of said vessel and ar- Ii ranged to eover said opening and the mouth oi said torpedo tube, the exterior surface of l lsaid rap being formed to conform to the eX- terior surface of the vessel, the said surfaces l together providing a Continuous uniform exterior surfaee for the vessel when said cap l is elosed. a shaft extending from the outside to the inside ot said vessel and provided With a worin at the outer end thereof meshing with .said gear, and a means positioned Within ysaid vessel for rotating said shaft and worin to operate said cap.
